On the improvement of solar cell based photovoltaic charger system

Due to the energy crisis, renewable energy sources have been deeply concerned as possible solutions to remain resources on the earth. Among these energy sources, solar energy, a free conversion, non-polluted and inexhaustible energy source, has been used to generate electricity for decades. However, the efficiency of solar cell is so far still low and how to make the photovoltaic chargers achieve the maximum of efficiency becomes worthwhile to research further. This paper focuses on the analyses of loading effects between photovoltaic (hereunder as PV) array module and pattern for series of batteries
